Be. it known 'that AUGUST J. Hime-Fiend acitizen of the United States of America,

residing at Los Angeles, county ci Los Angeles, State of Celifdrnim have invented c certain new andfuserful Ges-FuelCombustion 'Chamber Atteclieble to Het "lletcr Radiators; and l do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such'cs will. enable others skilled in the-nrt to which it appertains to ineke and use the mine.

This invention relates to e ges fuel com bustion chamber etteclieble to hot .Water radiators 'to convert tbe latter into ges heaters.

One object of' the invention is to provide l e novel and improved combustion chamber which can be readilyr attached to existingforlns of`liot 'Water radiators' so that fuel gas can be mede use of toprovide tbe heet- Further A*objects of the invention ere to'A provide a novel and im roved combustion chamber of the nature 'specied winch een be ettached tothe ordinary hot water radiator to form e gas fuel heater which is simple in construction, economical to instell and-meine odorless in use, convenient and sanitary, and highly edective -ior its pur ose.

Otlierolo'jects and the veA ventages'of the invention'will `be apperent to-tliose skilled in vthe vart gironi a. careful consideration of the following description o the preferred construction embodying the invention, taken in conledtion with' the accompanying draw Figure 1 is a front elevational view of the improved gas fuel combustion chamber ettached to' an ordinary hot water 'radiatorthe' latter being indicated by dotted lines; Fig. 2 is a sectional view of the combustion chamber,"taken on the line 2 2 of Fig. 1; .F ig. 3 is an enlarged broken sectional view taken on the line 3-3 'of Fig. 2; Fig. 4f is en enlarged broken side View of the lovver part of the combustion chember; Fig..v 51s en en@ Speccetion ci' Letters Potent.

As shown the drawings, the combustion chamber fl' 1s -provided in the upperrend lower parts thereof with .eide-"onanieren 8 I into which letter are fitted" the .nipple 9 whereby .the combustion .chamber 7 cen be easily and quickly attached centrallybetween the sections 1Q of an ordinaryhot.

Within the lower peri", of the 4combustion y'chamber 7 'is arranged* the burn ll. to

which is connected one 4end ofv the pipe- 152,-A which passes through an opening 13' in one side of 'the combustion chamber? and has on its'other end the Heringvtting 14 ntowlxichi 70 extends the gas fuel supply pipel which letter is providedwith the regulating valve 16 and the admission velved?.

The combustion chamber l is provided 'Ln' the-'interior thereof with .e ledge '18 on which rests ,the daring lower end portion 19 of the hood 20,A which latter is' open only et its 'upper and lower, ends and surrounds the upper part ofthe burner 11 and has its converging upper and portion 2l extending above-the bnrnjll, a's'shottn. Op osite to provided with openings or vents 22. The passngewa-ys Il" in the ripper part of the burner 1l extend substantially -parallelto vthe inner Well of the hood 2.0 so that" the gas flame is directed away from the inner well of the boodend toward the opening in the v topY end of the hood. To permit access to the burner 11 and the `placing of tlie hood 20 on the ledge 18, e door 23 1s provided etthe lower front part of the combustion chamber y 7'. Below the burner 1l in the combustion chamber 7 is arranged a l"-itting or piping 24 which is connected to the lower of the nipples 9 ,and to the outlet pipe 25 which connected at the rear' of "the combustion chamber 7- and to which is connected a flue,

instelled.

From/the foregoing descriptionthe ineny ner4 of use and the advantages of the inven-`l tion `Will be evident to those skilled in the; vgint, It will befseen thet the combustion' chamber eau he easily and quickly attached to the. ordinary hot Water radiator to oonvert the latter into a gas heater.

When the gas heater is in operation, air passes through the fitting 14C and mixes With the fuel gas iu the pipe l2. The heated products resulting from burning the gas tuellpass trom-the burner ll to the upper part of the combustion chamber 7 and thence pass downwardly through the sections-10 and thenoe through the piping 24E to the outlet pipe lVhen starting to operate the gas radiator the latter is filled with cold still air which causesA a hack pressure and consequently a choking ei'ect on the flame of the burner 1l, but the vents 22, see Fig. 3, permit the egress of a portion of the cold air so that the heated products of Combustion are enabled to quickly force their way through the radiator and remove the still air- When the gas radiator is in full operation some air is drawninto the radiator through the vents 22. Thehoo'd 2() shields the burner l1 'from back drafts due to gusts of Wind hy deflecting the hack drafts rhrorugh the rents 22, see Fig. 3, and thus l' ments putting out or' theijireliiuthe combustion rhamler T. lclaimf; gas oel combustion. ohaioher atachahle to hot water rath-tors to souffert 'the latter into gas heaters and provided with vente in thelower part thereof tor the purpose set forth, :1 gas burner in the combustion chamher, and a hood open only at its upper and.

lower ends, said hood disposed adjacent to said Vents and haviugf the lower end portion thereoiE fiar-iup; and surriuuiding the upper part of the burner aml having the upper erul portion thereoiI converging azul extending above the lun-ner. said huruer provided in the upper part thereof with passageway
